Survival Of The Unexpected: Darwin Revisited

Survival of the Unexpected: Darwin Revisited Lecture by Dorothy Wallace, Professor of Mathematics, Dartmouth College In many species of birds, the male sports much brighter plumage than the female. Darwin hypothesized that this is a result of "sexual selection" on the part of females of the species-also a belief broadly held by biologists. Superficially this plumage appears to be a disadvantage for the species, since bright males are easier targets for predators. New mathematical biology models show, however, that ordinary natural selection may suffice as an explanation of this phenomenon
